SPOKE-SOCKET.

Specification of Letters Patent.

Patented Jan. 25, 1910.

Application filed October 14, 1909. Serial No. 522,642.

To all whom "it may concern:

Be it known that I, JoIIN Mankwlok, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvementsin Spoke-Sockets; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in spoke sockets.

One object of the invention is to provide a spoke socket by means ofwhich a broken spoke may be quickly and easily taken out of the wheelrim.

Another object is to provide a spoke socket of this character which willbe simple, durable and inexpensive in construction, etlicient andreliable in operation and well adapted to the purpose for which it isdesigned.

VVith these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claim.

In the accompanying drawings, Figure 1 is a side view of a portion of awheel show ing the application of the invention; Fig. 2 is a centralvertical section on the line 22 of Fig. 1; Fig. 3 is a perspective viewof the socket showing the parts separated; and, Fig. 4: is an invertedperspective view of the wedge portion of the socket.

My improved spoke socket comprises a spoke engaging member consisting ofa tubular body portion or cap 1, closed at its outer end and having saidclosed outer end formed on an incline or at an oblique angle to the bodyportion. The body portion or cap 1, may be of any suitable shape tocorrespond with the cross-sectional shape of the spoke with which it isto be engaged.

On the closed outer end of the body portion or cap at one side of thesame is formed a longitudinally extending rim engaging lug 2, in theouter end of which is formed a rivetor bolt hole 3. In the closed outerend of the cap or body portion of the socket member at the opposite sideof the same from the lug 2, is formed an inwardly tapering groove orrecess 1, the purpose of which will be hereinafter described.

Adapted to cooperate with the spoke member to secure the outer end ofthe spoke in place is a wedge and rim engaging member consisting of awedge shaped plate 5, at one side of which is formed a longitudinallyextending substantially right-angular rim engaging lug G, whichcorresponds in size and shape to the rim engaging lug 2, of the spokesection and when in operative position is opposite to and in alinementwith said lug The lug (3, is provided with a rivet or bolt hole 6,disposed in line with the rivet or bolt hole 3, in the lug 2, when theparts are in operative position. The plate 5, of the rim engaging memberpreferably corresponds in size and shape to the closed outer end of thespoke member or cap of the socket with which end the plate is engagedwhen the parts are assembled. On the lower or inner side of the plate 5,adjacent to its outer edge is formed an inwardly tapering projection orlug 7, which, when the plate 5,

is in engagement with the outer end of the cap 1, will fit into thegroove or recess 4t, thus forming an interlocking connection betweensaid plate and the end of the cap, whereby the rim engaging member ofthe socket is held against lateral movement or displace ment on thespoke member of the socket.

\Vhen the socket is arranged for use, the cap or body portion 1, isengaged with the outer end of a spoke and is preferably secured in placeon said end by a bolt or rivet S, which is passed through aliuedapertures 9, formed in the opposite sides of the body portion 1. Theheads of the rivet S, are preferably countersunk or lie flush with theouter sides of the body portion as shown. After the cap or body portion1, has been engaged with the spoke, the inner end of the spoke isengaged with the hub in the usual or in any suitable manner, while thelug 2, on the cap 1, of the socket, is engaged with one side of thewheel rim. \Vith the parts in this position, the wedge plate 5, of therim engaging member is forced between the end of the cap member and theinner edge of the rim until the lug (3, on the plate 5, is in engagementwith the adjacent side of the wheel rim and in a position directlyopposite to the lug 2, on the cap. A hole is bored through the rim inalinement with the bolt or rivet holes in the outer ends of the lugs 2,and 6, and through said holes is inserted a bolt or rivet 10, the headsor ends of Which are countersunk in the lugs and lie flush with theouter surface thereof.

By means of a socket constructed as herein shown and described, a brokenspoke may be readily removed from the wheel and a new spoke insertedwithout removing the tire and rim, thus saving a great amount of time,labor, and expense.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claim.

Having thus described my invention, what I claim is:

In a spoke socket, a spoke engaging member comprising a tubular bodyportion or cap having a closed outer end formed at an oblique angle tosaid body port-ion, a tapered recess in the end of said body portion, anapertured lug on the outer end of one side of the said body portion, acombined Wedge plate and rim engaging member comprising a wedge shapedplate adapted to be driven between the outer end of said body portionand the adjacent edge of the wheel rim, a tapered lug formed on saidWedge plate to engage the tapered recess in the end of the socket, anapertured rim engaging lug formed on said plate, a rivet arrangedthrough the apertures in said lugs and through the Wheel rim, and meansto secure the cap or body portion in engagement with the end of thespoke.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
